Aleksey Plekhanov updated IGNITE-12572:
---------------------------------------
Fix Version/s: (was: 2.9)
> Get rid of synchronous cache destroying in multiple caches group.
> -----------------------------------------------------------------
>
> Key: IGNITE-12572
> URL: https://issues.apache.org/jira/browse/IGNITE-12572
> Project: Ignite
> Issue Type: Improvement
> Affects Versions: 2.7.6
> Reporter: Alexey Scherbakov
> Priority: Major
>
> Current implementation of destroying a cache belonging to multiple caches
> group is done synchronously in exchange worker and blocks exchange events
> processing [1].
> This has negative impact on grid availability if topology is changed during
> this process.
> Proposed solution: make cache destroying asynchronous, similar to partition
> eviction. Same mechanics can be reused for clearing partition of destroyed
> cache data.
> Special attention should be given to the case then cache is recreated while
> being destroyed.
> The idea is to continue clearing of old data asynchronously and insert new
> data using new cache generation. This can be achieved for example by
> implementing unique key prefixes for each cache generation.
